Popis: Eight biogenic amines (spermine, spermidine, putrescine, histamine, tyramine, phenylethylamine, cadaverine and serotonin) were determined by LC-UV after derivatization with dansyl-chloride in both ground coffee and coffee beverages obtained by different methods. In ground coffee, the most relevant amine was PUT, followed by SPD, HIS, TYR, CAD, SPM, PHE, and SER, with the total BAs content decreasing as the roasting degree increased. In coffee brews, the order was PUT, SPM, TYR, CAD, SPD, PHE, HIS, and SER, but at a very low level in comparison with the amount of BAs determined in roasted ground coffee. Beverages prepared by espresso, capsule, and pod machines had the lowest BAs contents, as a result of the thermal and physical stress imposed on ground coffee by these methods, while mocha contained the highest BAs amounts owing to lower pressure and longer brewing time.
